Thermosiphons offer more cost-efficient two phase cooling than heat pipes or vapor chambers, but as they are wickless, they need a consistent gravitational pull to operate. For additional cost savings, Aavid, Thermal Division of Boyd Corporation offers advanced engineering and streamlined manufacturing that can enable one shot brazing. Aavid also offers loop thermosiphon solutions for passive liquid cooling for more reliable high power cooling.
